The only known ways to battle Oak are by performing the {{DL|Mew glitch|Ditto glitch}} with a {{stat|Special}} stat of 226 or by performing the [[old man glitch]] with {{MN}} as the character in the 3rd, 5th or 7th slot of the player's name. These teams cannot be battled when using the old man glitch; they can only be battled via the Ditto glitch if the wild Ditto's {{stat|Attack}} is lowered by 4, 5, or 6 stages (each will yield a different one of the three teams).

Professor Samuel Oak (Japanese: オーキド・ユキナリ博士Dr. Yukinari Okido, Ōkido-Hakase and Orchid are also seen) is a Pokémon Professor who lives and works at his research lab in Pallet Town of the Kanto region. According to Professor Elm, Oak concentrates on Pokémon and human relationships as a profession.

In the games

In Generation I

The unused Trainer class for Professor Oak. However, in this case the game has not changed the battle mode data to a Trainer battle, so if "captured" he would be read as the last normal Pokémon encountered.

He was a childhood friend of Agatha. They remained good friends and top-class Pokémon Trainers until Oak stopped battling and became interested in Pokémon research. Agatha said that he became soft and started to regard him as a fool. However, Oak still affiliates with the Pokémon League as an adviser.

Pokémon

Red, Green, and Blue

Professor Oak confirms having been a successful Trainer in his youth; however, he states that he only possesses the following Pokémon. Red is allowed to choose one in order to begin his journey. His grandson, Blue, the player's rival, then picks the Pokémon whose type has an advantage against their own.

Unused teams

In the Generation I games there is unused Trainer data for Prof. Oak. This implies that Oak was originally going to be able to be battled.

In the data, Oak has Level 66 Tauros, Level 67 Exeggutor, Level 68 Arcanine, Level 70 Gyarados and one of the Kanto starters at Level 69. This places his strength on-par with the player's rival and the Pokémon League Champion. As well, four of his Pokémon are identical to the ones used by the Champion, only higher level, so originally Oak may have been intended to be in the game as the Champion, or at least another high-ranking Trainer.

The only known ways to battle Oak are by performing the Ditto glitch with a Special stat of 226. These teams cannot be battled when using the old man glitch; they can only be battled via the Ditto glitch if the wild Ditto's Attack is lowered by 4, 5, or 6 stages (each will yield a different one of the three teams).

In Generation II

Professor Oak was always well-known in Kanto but in Generation II he became more of a celebrity, a "star Pokémon Researcher". He became famous in Johto because of his Radio Show with DJ Mary. He was going to turn down the show at first but Mary's energy and persistence wore him down. Ethan/Kris first met him visiting the home of Mr. Pokémon, another of Oak's childhood friends. Later he grants the young Trainer access to Mt. Silver, a place which only the finest Pokémon Trainers may enter, after the player has earned all the Badges in Johto and later Kanto.

Professor Oak has many old friends. One of them is Kurt, a Poké Ball smith from Azalea Town and another is Professor Elm who used to be Oak's assistant. In fact, there is a picture on Kurt's wall saying "...a young Prof Oak?" and an email addressed to him from Professor Elm can be found in his lab:

"But, I… Oh, all right then. That Pokémon is yours. I was going to give you one anyway… <player>, come over here. <player>, this is the Pokémon I caught earlier. You can have it. I caught it in the wild and it's not tame yet."

"What? Would you look at that! It's odd, but it appears that your Pikachu dislikes Poké Balls. You should just keep it with you. That should make it happy! You can talk to it and see how it feels about you.

"Oh, <player>! How is my old Pokémon? Well, it seems to like you a lot. You must be talented as a Pokémon trainer! What? You have something for me? Ah! This is the custom Poké Ball I ordered! Thank youRB

You have forgotten to treat your Pokémon with trust and love! Without them, you will never become a champ again! <player>! You understand that your victory was not just your own doing!

"Hello! Sorry to keep you waiting! Welcome to the world of Pokémon! My name is Oak. People call me Pokémon Prof. This world is inhabited by creatures that we call Pokémon. People and Pokémon live together by supporting each other. Some people play with Pokémon, some battle with them. But we don't know everything about Pokémon yet. There are still many mysteries to solve. That's why I study Pokémon every day. Now, what did you say your name was? <player>, are you ready? Your own very Pokémon story is about to unfold. You'll face fun times and tough challenges. A world of dreams and adventures with Pokémon awaits! Let's go! I'll be seeing you later!"

Aha! So you're <player>! I'm Oak! A Pokémon researcher. I was just visiting my old friend Mr.Pokémon. I heard you were running an errand for Prof.Elm, so I waited here. Oh! What's this? A rare Pokémon! Let's see… Hm, I see! I understand why Prof.Elm gave you a Pokémon for this errand. To researchers like Prof.Elm and I, Pokémon are our friends. He saw that you would treat your Pokémon with love and care. …Ah! You seem to be dependable. How would you like to help me out? See? This is the latest version of Pokédex. It automatically records data on Pokémon you've seen or caught. It's a hi-tech encyclopedia! Go meet many kinds of Pokémon and complete that Pokédex! But I've stayed too long. I have to get to Goldenrod for my usual radio show. <player>, I'm counting on you!"

Ah, <player>! It's good of you to come all this way to Kanto. What do you think of the trainers out here? Pretty tough, huh? Ah, you're collecting Kanto Gym Badges.

Intro

"Hello, there! Glad to meet you! Welcome to the world of Pokémon! My name is Oak! People affectionately refer to me as the Pokémon Professor. This world… …is inhabited far and wide by creatures called Pokémon! For some people, Pokémon are pets. Other use them for battling. As for myself… I study Pokémon as a profession. But first, tell me a little about yourself. Now tell me. Are you a boy? Or are you a girl? Let's begin with your name. What is it? Right… So your name is <player>. This is my grandson. He's been your rival since you both were babies. …Erm, what was his name now? …Er, was it <rival>? That's right! I remember now! His name is <rival>! <player>! Your own very Pokémon legend is about to unfold! A world of dreams and adventures with Pokémon awaits! Let's go!"

After resuming game after beating rival before receiving National Pokédex, if the Sevii sidequest is not done:

"Ah, <player>! You seem to be enjoying traveling. Knowing you, <player>, I can easily imagine you going out to even more exotic locales. Good for you, good for you. Hohoho."

After resuming game after beating rival before receiving National Pokédex, if the Sevii sidequest is done with fewer than 60 Pokémon owned:

"Ah, <player>! You're back, are you? How much have you filled in your Pokédex? May I see it? Let's see… You've caught <number of owned Pokémon>… Hm, it looks as if you're putting in an honest effort. When you manage to fill it some more, come show me, please."

After resuming game after beating rival before receiving National Pokédex, if the Sevii sidequest is done with 60 or more Pokémon owned:

"Ah, <player>! You're back, are you? How much have you filled in your Pokédex? May I see it? Let's see… You've caught… <number of owned Pokémon>!? Now, this is impressive! There's something I wanted to ask of you, <player>. Come. Follow me.

Battle

"Oh, for Pete's sake… So pushy, as always. <player>. You've never had a Pokémon battle before, have you? A Pokémon battle is when Trainers pit their Pokémon against each other. The Trainer that makes the other Trainer's Pokémon faint by lowering their HP to ‌“0,” wins. But rather than talking about it, you'll learn more from experience. Try battling and see for yourself."

Damaging move used for first time:

"Inflicting damage on the foe is the key to any battle. "

Stat-lowering move used for the first time:

"Lowering the foe's stats will put you at an advantage."

Party screen is shown for first time (via either Pokémon button or using Potion):

"It's important to get know your Pokémon thoroughly. This is a list of your Pokémon, <player>. Open this to check the skills and moves of your Pokémon. You also choose Pokémon here if you want to use an item on one."

Pokémon is healed via Potion:

"Keep your eyes on your Pokémon's HP. It will faint if the HP drops to “0.”

If player tries to run:

"No! There's no running away from a Trainer Pokémon battle!"

Battle is won:

"Hm! Excellent! If you win, you earn prize money, and your Pokémon will grow! Battle other Trainers and make your Pokémon strong!"

Battle is lost:

"Hm! How disappointing… If you win, you earn prize money, and your Pokémon will grow. But if you lose, <player>, you end up paying prize money… However, since you had no warning this time, I'll pay for you. But things won't be this way once you step outside these doors. That's why you must strengthen your Pokémon by battling wild Pokémon. "

Overworld

After getting dragged into lab:

"<rival>? Let me think… Oh, that's right, I told you to come! Just wait! Here, <player>! There are three Pokémon here. Haha! The Pokémon are held inside these Poké Balls. When I was young, I was a serious Pokémon Trainer. But now, in my old age, I have only these three left. You can have one. Go on, choose!

Be patient! <rival>. You can have one, too!"

Before choosing starter:

"Now, <player>. Inside those three Poké Balls are Pokémon. Which one will you choose for yourself?"

If player tries to go away before choosing starter:

"Hey! Don't go away yet!"

When choosing Bulbasaur:

"I see! Bulbasaur is your choice. It's very easy to raise. So, <player>, you want to go with the Grass Pokémon Bulbasaur?

"If a wild Pokémon appears, your Pokémon can battle it. With it at your side, you should be able to reach the next town."

If talked to after battling rival:

"<player>, raise your young Pokémon by making it battle. It has to battle for it to grow."

After receiving Oak's Parcel:

"Oh, <player>! How is my old Pokémon? Well, it seems to be growing more attached to you. You must be talented as a Pokémon Trainer. What's that? You have something for me? Ah! It's the custom Poké Ball! I had it on order. Thank you!

"Oh, right! I have a request for you two. On the desk there is my invention, the Pokédex! It automatically records data on Pokémon you've seen or caught. It's a high-tech encyclopedia! <player> and <rival>. Take these with you. You can't get detailed data on Pokémon by just seeing them. You must catch them to obtain complete data. So, here are some tools for catching wild Pokémon. When a wild Pokémon appears, it's fair game. Just throw a Poké Ball at it and try to catch it! This won't always work, however. A healthy Pokémon can escape. You have to be lucky! To make a complete guide on all the Pokémon in the world… That was my dream! But, I'm too old! I can't get the job done. So, I want you two to fulfill my dream for me. Get moving, you two. This is a great undertaking in Pokémon history!

When receiving National Dex:

"Ah, now this is excellent! <player>, I have another important favor to ask of you. I need you to listen closely. Recently there have been sightings of many rare Pokémon species. I'm talking about Pokémon that have never been seen in Kanto. I would love to go see things for myself, but I'm much too old. Since I can't do it, <player>, I'd like you to go in my place.

"I know, I know. Of course I need your help, too. Now, I need to see both your Pokédexes. … … … … … … … … … … … … …And that's done! Now these units can record data on a lot more Pokémon. Now, <player> and <rival>! This time, you must really must work towards filling your Pokédexes. I urge you to make them the best and the most complete of all time! Truly, this is a monumentally great undertaking in Pokémon history!

"<player>! So, you've won! Sincerely, congratulations! You're the new Pokémon League Champion! You've grown up so much since you first left with <starter> to work on the Pokédex. <player>, you have come of age! <rival>… I'm disappointed in you. I came when I heard you'd beaten the Elite Four. But, when I got here, you had already lost! <rival>, do you understand why you lost? You have forgotten to treat your Pokémon with love and trust. Without them, you will never become a Champ again! <player>. You understand that your victory was not just your own doing. The bond you share with your Pokémon is marvelous. <player>! Come with me!"

Er-hem! Congratulations, <player>! This floor is the Pokémon Hall of Fame. Pokémon League Champions are honored for their exploits here. Their Pokémon are also recorded in the Hall of Fame. <player>! You have worked hard to become the new League Champion. Congratulations, <player>, you and your Pokémon are Hall of Famers!

"And with that... I'm Professor Oak, a Pokémon researcher! So you're <player>! I was just visiting my friend Mr. Pokémon. I heard you were running an errand for Professor Elm, so I waited here. Oh!

He also shows up in Hey You, Pikachu!, where he enlists the player to help test a translation device called the PokéHelper, using a wild Pikachu as the main research subject. He is also the person who launches the Pokémon Channel project in the game of the same name, and tuning into the "Oak's Report" channel allows the player to save their game.
